Wow Calculating Block Rating

As you can see, the block % is not as high, but the block amount is much higher.Â The first thing we will do is calculate a block rating for each shield, which tells us the average amount of damage a shield blocks with each hit.Â To do so, we simply get the average block amount(blockamt1+blockamt2)/2 and multiply it by the chance to block. So for each shield we have:
Stormshield Block Rating =Â 1049.44 = (2800+3759)/2 * 0.32
Sacred Shield Block Rating =Â 1219.74 = (3706+4706)/2 * 0.29

So on average, the sacred shield nullifies 170.3 more damage per hit than the stormshield.Â So, its true that we arenâ€™t factoring in the other stats from stormshield yet, but what happens when we factor in +% block items?Â Letâ€™s add helm of command and a justice lantern into the mix for an additional 19% block.

As you can see, the difference has grown to 346.33 more damage per hit blocked than stormshield.Â So if you can get a sacred shield with the same stats as the stormshield, it would be a clear pick to go with the sacred shield.
